Recover Windows 7 from a serious error. If your computer won't start Windows at all, you can access Startup Repair and other tools in the System Recovery Options menu from the Windows 7 installation disc or USB flash drive. These tools can help you get Windows 7 running again.

What is Startup Repair?

Startup Repair is a Windows recovery tool that can fix certain system problems that might prevent Windows from starting. Startup Repair scans your computer for the problem and then tries to fix it so your computer can start correctly.

Startup Repair is one of the recovery tools in the System Recovery Options menu. This set of tools is located on your computer's hard disk and on the Windows installation disc.

Are there problems that Startup Repair can't fix?

Startup Repair can only fix certain problems, such as missing or damaged system files. It can't fix hardware failures, such as a failing hard disk or incompatible memory, nor does it protect against virus attacks.

Startup Repair isn't designed to fix Windows installation problems, nor is it a backup tool, so it can't help you recover personal files, such as photos or documents. To help protect your computer, back up your system and files regularly. For more information, search for "backup" in Windows Help and Support.
